In this paper, the voltage-mode universal filter employing the active building block, called voltage differencing differential difference amplifier (VDDDA) is introduced. The proposed circuit configuration has single output voltage node and five input voltage nodes. All input voltage nodes exhibit high impedance with low output impedance of the output voltage node, which is completely cascaded without...
The grounded inductance simulators using available commercially integrated circuit (IC) are proposed in this paper. The three types of active inductor called parallel R and L, series R and L and pure L are achieved. The proposed inductance simulators consist of single available commercially IC from Linear Technology Inc. called LT1228 with a resistor and a capacitor. The tune of inductance and resistance...
